Survival analysis and gender differences in hypertrophic cardiomyopathy proband patients referred for genetic testing.

Background: Hypertrophic cardiomyopathy (HCM) is believed to have low overall mortality rate, that could be influenced by gender, particularly among probands. We aimed to evaluate the survival rates and possible gender differences in a homogeneous cohort of HCM proband patients, referred for genetic testing, from the same geographical area, without differences in medical care access nor clinical referral pathways.

Methods: we compared the mortality rates of a cohort of consecutive HCM probands referred for genetic testing (2000-2022), from a Spanish region (xxx1) with a centralized genetic testing pathway, with its control reference population by Ederer II method.

Sonography of a case series of talar callosities.

Talar callosity is an uncommon condition characterized by asymptomatic hyperkeratotic plaques located on the dorsum of one or both feet. We have detected an increased number of children presenting with this condition after the COVID-19 lockdown. High-frequency ultrasound was performed in all patients who consulted because of talar callosity.

Double nail of the second toe: A case report with sonographic and radiological correlation.

Double toenail is a rare abnormality that usually affects the fifth toe. It is considered as an inherited condition that may represent an incomplete form of polydactyly. Underlying bone abnormalities should be ruled out.

Dermatologic ultrasound in the management of childhood linear morphea.

Linear morphea is the most common subtype of localized scleroderma in the pediatric population. This condition can be quite disabling, with complications such as growth defects and painful flexion contractures. Assessment of disease progression and early intervention are key to minimize morbidity.
